parq_blockmodel.mesh.glb.write_glb(mesh, output_path, texture_attribute=None, colormap='viridis', include_metadata=True)[source]#

Write a TriangleMesh to GLB (glTF 2.0 binary) format.

This generates a single-file GLB suitable for viewing in standard 3D viewers (Babylon.js, Three.js, etc.). Optionally applies vertex colors based on a scalar attribute.

Parameters:

  • mesh (TriangleMesh) – The mesh to write.

  • output_path (str or Path) – Path to the output .glb file.

  • texture_attribute (str, optional) – If provided, vertex attribute to use for coloring (e.g., “grade”). Colors are mapped via the specified colormap.

  • colormap (str, default "viridis") – Matplotlib colormap name for texture_attribute mapping. Only used if texture_attribute is specified.

  • include_metadata (bool, default True) – If True, embed mesh metadata in glTF extras.

Raises:

ValueError – If the mesh is invalid or attribute is not found.

Return type:

None
